Wireless telecommunications system

Abstract

A wireless telecommunications system including first and second groups of terminal devices operable to communicate with a base station via respective first and second network nodes. Each of the first and second groups of terminal devices are synchronized to communicate with the first and second network nodes, respectively, in a discontinuous mode including a repeating signalling cycle including first and second wake periods. The first wake period is a first portion of the repeating signalling cycle and the start of the first wake period is defined by a first offset value relative to the start of the repeating signalling cycle. The second wake period is a second portion of the repeating signalling cycle and the start of the second wake period is defined by a second offset value relative to the start of the repeating signalling cycle, being different from the first offset value.

Description

TECHNICAL FIELD OF THE DISCLOSURE[0001]The present disclosure relates to a wireless telecommunications system.BACKGROUND OF THE DISCLOSURE[0002]Mobile communications system (or wireless telecommunications system) such as those which are being developed in accordance with the Long Term Evolution (LTE) project by the Third Generation Project Partnership (3GPP) can provide a facility for communications devices to transmit or receive data for a variety of applications with high data rates within a radio coverage area provided by a mobile communications network. A wireless access interface provided by the mobile communications network configured in accordance with an LTE standard includes signal transmission techniques which can support these high data rates. There is therefore expected to be a variety of applications, which can be supported by an LTE system.[0003]Although there are applications which require high data rates to support their operation, there are some applications in whic...

AI Technical Summary

Benefits of technology

The present invention provides a wireless telecommunications system with two groups of terminal devices that communicate with a base station using a repeating signalling cycle. The first group of terminal devices communicates with the base station during a first wake period of the repeating signalling cycle, while the second group of terminal devices communicates with the base station during a second wake period. The first and second groups of terminal devices are synchronized to communicate with the base station during their respective wake periods. The system allows for discontinuous mode communication between the terminal devices and the base station, where the terminal devices exchange predetermined signalling with the network node during specific periods of the repeating signalling cycle. The system also includes a controller that selects which group of terminal devices to communicate with the base station based on information stored in a storage medium or measured from a direct signaling from the base station. The technical effect of the invention is to improve the efficiency and reliability of wireless communication in a wireless telecommunications system.

Problems solved by technology

Such devices may also be deployed in locations in which radio communications conditions can make transmission and reception of signals more difficult.

Problems therefore arise in trying to efficiently manage the data transmitted to and from such a large number of devices on the network.

There are also continued problems in trying to decrease the power consumption of MTC devices.
